` l.'7. Claims.

This invention relates to shavers and particularly to a guard forprotecting the shaving head or heads thereon.

The invention comprehends the provision of a guard for a shaver headarranged for detachable mounting on the shaver case to be normallysupported in spaced relation over the heads on shavers in such a waythat in case the end carrying the shaver head or heads is accidentallyengaged with another object, the guard will receive the force of impact.

The invention comprehends the provision of a guard for the heads ofshavers having interengaging parts on the case of the shaver and theguard so that flexing of the guardfwill engage and disengage the partsin cletachably mounting the guard on the shaver in position to protectthe shaver heads from damage by impact with other objects.

The invention comprehends a guard for shavers having a head protectingsection and side sections extending from opposite sides thereof insubstantially parallel relation formed with parts `for cooperativeengagement with parts on the casing of the shaver to detachably securethe guard in position on the shaver to guard the head or heads thereon,the structure being flexible so that the parts may be engaged anddisengaged in a convenient manner for detaching and applying the guardto the shaver. l

'I'he invention comprehends the provision of a guard wherein sidesections extending from the head protecting section are formed atopposite ends with laterally extending protecting flanges that simulatethickness at the sides of the shaver and provide for the transmission ofshock applied to theguard at the sides and corner portions direct to thecasing through the flanges as well as provide a thickness simulatingstructure at the ends of the guard so that it may be more readilyengaged for manual attachment and removal from the shaver.

The guard of this invention further comprehends the provision of a headprotecting section particularly adapted for use with multiple headshavers wherein a series of separate sections may be provided so thatone will cover and protect each shaver head while longitudinal ribs areformed on the guard intermediate these head protecting sections withside sections at the opposite sides of the guard formed with partscooperating with parts of the casing to detachably secure the guard inhead protecting position on the shaver.

The invention comprehends a number of other magnetic motor (not shown).

features of construction that will be hereinafter pointed out andclaimed in the following description and claims, all of the featuresbeing cooperative with those referred to above in providing a head guardfor shavers that may be constructed in an economical manner and which isconvenient for use.

In the drawing:

Fig. 1 is a side elevation of ashaver with the head guard appliedthereto.

Fig. 2 is an enlarged fragmentary side elevation of a side adjacent tothat shown inFig. 1, with portions broken away, shown in cross section,and illustrating the head guard in cross section in assembled ,positionon the shaver.

Fig. 3 is a top plan view of the head guard. Fig. 4 is a bottom planview of the head guard. Fig. 5 is an end elevation of the head guard. ,yFigu is a longitudinal fragmentary cross section through the headprotecting section of the 'guard and the adjacent shaving section of ashaver head.

A conventional form of electric dry shaver is illustrated in the drawingin which casing l forms the usual handle and the housing for the drivingmeans for the shaver which may be in the form of the usual make andbreak contact type of electro- One end of casing l is formed withone ormore channels formed to provide a seat for receiving and mounting ashaver head at 2u in each channel.

The drawing illustrates a shaver with three channels arranged in spacedparallel relation transversely across one end of the casing forreceiving three shaver heads 2 as will be particularly apparent from thedisclosure in Fig. 2. These shaver heads 2 may be detachably mounted ineach channel in independent relation in a manner well-known in the art.Each shaver head comprises a base portion 3 engaged in the channel incasing .I and/an outwardly projecting shaving section 4 formed in aconventional manner with cutter bars (not shown). The ends of eachshaver head 2 have reinforcing ribs beyond the shaving section as shownin Fig. 6 which project outwardly beyond the outer surface of theshaving section.

An inner movable cutter 5 is mounted on the inside of shaving section 4in a conventional manner well-known in the art and has cutter bars (notshown) for cooperation with the cutter bars on shaving section I forcutting cooperation therewith when inner cutter l 5 is reciprocated backand forth relative to shaving section 4. Any suitable means may beprovided for securing each shaver head 2 detachably in the channel inthe end of casing I, such means not .being illustrated because it doesnot form part of the present invention.

The drawing also illustrates the shaver as being provided with hairpockets 6 to cover the oppovsite open ends of shaver heads 2 in order toreeach shaver head. In the illustration shown in s the drawing guard "Iis provided with three sec- -tions 8 of partially cylindrical shape incross section. The central section 8 is joined with the two sidesections 8 in the manner clearly illustrated in Figs. 2, 4 and 5, bymeans of a longitudinally extending rib 9, two such ribs being used .tosecure the three sections together. This rib is oi considerably thickercross section, as illustrated in Fig. 2, than head protecting sections 8in order to form a substantially rigid guard structure longitudinally ofthe head.

At opposite sides of the guard, head `protecting sections 8 are formedwith laterally extending side sections I0 extending laterally from theouter side edges of sections 8 in a manner shown in Figs. k2 and 5. Sidesections III extend in substantially parallel relation to each other, asshown in Figs. 2, 4 and 5, and with sections 8 and ribs 9 extendthroughout the length of shaver heads 2, as illustrated in Fig. 1. Sidesections HI have a greater cross section than head protecting sections 8in order to make them substantially inexible while sections 8 are formedto be resiliently flexible in order to provide for a limited movement ofthe free edges of side sections I8 toward and from each other. Theresiliency of the guard structure in head protecting sections 8 is suchas to normally maintain side sections IIIv rin the parallel relationillustrated in Fig. 2.y l v l The central portions of side sections IIIare formed with inwardly extending projections II having upper and lowerinclined faces I2 and I3 respectively, arranged to form part ofcomplementary interengaging parts or securing means for attaching theguard to shaver casing I. Shaver casing I is provided on opposite sidesnear the end mounting shaver heads 2 with a plurality of outwardlyextending transverse ribs I4 arranged in spaced relation and designed toprovide a decorative effect on the exterior of casing I. Rib I4 nearestto the end of casing I mounting shaver heads 2 and the groove I5 betweenthis rib and the next adjacent rib, is so constructed that projectionsvIIon guard I will engage in grooves I5 at opposite sides of casing Ibetween adjacent ribs I4 forming groove I5.

Through the cooperation of ribs I4 forming one set of complementaryparts or securing means to coact with projections II forming the otherpart of the securing means effective means is provided for retainingguard 'I detachably secured on shaver casing I in a position to protectshaver heads 2. In order to enhance the appearance of the shaver, guardI has the lower edges of side flanges I0 slightly-curved to conform fshaver structure and reduce the to the curvature of ribs I4 asillustrated in Fig. 1.

Thickness simulating and protective flanges Il are formed at oppositeends of side sections III and extend laterally inward therefrom in amanner shown in Figs. 2, 4 and 5, being formed lntegrally at the upper`edges with adjacent portions of head protecting sections 8 where theyextend to and merge into side sections I0. These flanges I6 provide forthe convenient manual en' gagement of ones lingers with the guard memberfor flexing the guard member in attachment and removal thereof from theshaver. In addition, these flanges I6 are arranged in perpendicularrelation to the adjacent portions of shaver casing I and hair pockets 6.These flanges are arranged so that if the end of shaver carrying head 2is engaged with another object accidentally, the guard will receive andtransmit the force of such engagement when at the sides of the `shaverand at the end adjacent to sides, directly to the casing in order toprotect the shaving section 4 of each shaver head from damage.

The head protecting sections 8, ribs 9 and side sections I0 alsocooperate in receiving and distributing the force of impacts against theend of the shaver carrying the heads 2 so that imi the end of the,

pacts will be distributed over tendency of impacts from breaking some ofthe cutter bars. The ends of sections 8 will engage the ribs at the endsof shaver heads 2 in distributing impacts on the guard in order toprotect the shaving section with its cutter bars.

vGuard I may be molded of suitable plastic material such as any ofthematerials from the thermo-plastic group as well as any of the materialscommonly identified as thermo-setting plastics. It is to be understoodthat guard 'I may be made of sheet metal, or drawn, forged or cast.

The inherent resiliency of the material including the -form ofconstructionl of head protecting sections 8 provides guard 'I with asuitable and desirable resiliency andfiexibility that enables the readyremoval and application of the guards to the shaver. In applying theguard` to the shaver it is merely placed over the end ofthe shavercarrying heads 2 and pushed into the position shown inv Fig. 2. Inpushing it toward the position shownin Fig. 2 from a position above thatillustrated, the inclined faces I3 will cam side sectionsl yII'Ioutwardly over uppermost rib I 4 as shown in Fig. 2 so that projectionsII will drop into grooves I5 and detachably secure guard 'I in position.In removing the guard from the shaver inclined faces I2 will operate tocam projectionsl II`out of groove I5 when the guard is pushed away fromthe end of the shaver in any desired manner. The guard may also begripped at the ends of a side section I0 and manually ilexed outwardlyto disengage projections II from grooves I5 and ribs I4 in removing theguard.
